"Suspect" is a little misleading because it can be interpreted to mean the deer was behaving or appearing abnormally. However, DNR is using the term "Suspect" to identify those deer that tested positive using the initial screening test used by the DNR. The way it was explained to me is that it is a biochemical test with a sort of color change that indicates a positive result. Anything that is not a clear negative is sent to Iowa for confirmation. However, the person I spoke to said every positive initial test had been very obvious - no borderline results. There have not been any false initial positives yet, so it seems to be a reliable screening test. However, it is a chemical indicator test, so there is always the potential for a contaminant to create the appearance of a positive indicator, so they go to Iowa for a more exact test. In other words, "suspect" doesn't refer to anything outwardly suspicious about the deer. Just the test result.
